Weak Deflection Angle and Shadow by Tidal Charged Black Hole
Universe, 2021 In this article, we calculate the deflection angle of a tidal charged black hole (TCBH) in weak field limits. First, we obtain the Gaussian optical curvature and then apply the Gauss–Bonnet theorem on it.

Strong-Coupled Relativity Without Relativity [PDF]
General Relativity and Gravitation, 2004 GR can be interpreted as a theory of evolving 3-geometries. A recent such formulation, the 3-space approach of Barbour, Foster and Murchadha, also permits the construction of a limited number of other theories of evolving 3-geometries, including conformal gravity and strong gravity.

International Journal of Modern Physics A, 2003 A possible resolution of the incompatibility of quantum mechanics and general relativity is that the relativity principle is emergent. I show that the central paradox of black holes also occurs at a liquid-vapor critical surface of a bose condensate but is resolved there by the phenomenon of quantum criticality.

Nonanalytic Relativistic r-Modes of Slowly Rotating Nonbarotropic Neutron Stars
Universe, 2022 We show that the r-modes of slowly rotating nonbarotropic neutron stars are described by nonanalytic functions of stellar angular velocity, which makes the perturbation techniques, used so far in the r-mode theoretical studies, inapplicable.

Some comments on the universal constant in DSR [PDF]
, 2006 Deformed Special Relativity is usually presented as a deformation of Special Relativity accommodating a new universal constant, the Planck mass, while respecting the relativity principle. In order to avoid some fundamental problems (e.g.

From Black Holes Entropy to Consciousness: The Dimensions of the Brain Connectome
Entropy, 2023 It has been shown that the theory of relativity can be applied physically to the functioning brain, so that the brain connectome should be considered as a four-dimensional spacetime entity curved by brain activity, just as gravity curves the four ...

Communications in Contemporary Mathematics, 2001 This paper achieves, among other things, the following: • It frees the main result of [9] from the hypothesis of determinant class and extends this result from unitary to arbitrary representations. • It extends (and at the same times provides a new proof of) the main result of Bismut and Zhang [3] from finite dimensional representations of Γ to ...

Indagationes Mathematicae (Proceedings), 1951 If one keeps angle but drops an invariant (four-dimensional) length from an essentially Einstenian description of the world, one gets Conformal Relativity. (The invariance of angle is all that is required by the «invariance of the light cone» for physically equivalent observers). The Special Theory of Conformal Relativity studies the conformal geometry,

Einstein Geometrization Philosophy and Differential Identities in PAP-Geometry
Advances in Mathematical Physics, 2016 The importance of Einstein’s geometrization philosophy, as an alternative to the least action principle, in constructing general relativity (GR), is illuminated. The role of differential identities in this philosophy is clarified.

STABILITY OF STELLAR SYSTEMS ORBITING SGR A*
Odessa Astronomical Publications, 2016 Path equations of different orbiting objects in the presence of very strong gravitational fields are essential to examine the impact of its gravitational effect on the stability of each system.
